BUMAX Lock is an all-metal lock nut made from the same stainless steel grade as BUMAX® 88.

It is equipped with a specially designed thread profile that locks when it is tightened, distributing the stresses along the entire nut thread. This allows better load distribution which in turn produces greater gripping strength. The nut is also free spinning when threading on a bolt, which allows faster mounting.

IMPORTANT: To achieve the correct locking function, the BUMAX Lock must be assembled with a flange or collar down.
